They may perform other operations too, such as locating +and retrieving a @acronym{S/MIME} certificate of the person you wish to +send encrypted mail to. When the mml parsing engine converts your +@acronym{MML} into a properly encoded @acronym{MIME} message, the secure +tag will be replaced with either a part or a multipart tag. If your +message contains other mml parts, a multipart tag will be used; if no +other parts are present in your message a single part tag will be used. +This way, message mode will do the Right Thing (TM) with +signed/encrypted multipart messages. + +Since signing and especially encryption often is used when sensitive +information is sent, you may want to have some way to ensure that your +mail is actually signed or encrypted. After invoking the above +sign/encrypt commands, it is possible to preview the raw article by +using @kbd{C-u C-c RET P} (@code{mml-preview}). Then you can +verify that your long rant about what your ex-significant other or +whomever actually did with that funny looking person at that strange +party the other night, actually will be sent encrypted. + +@emph{Note!} Neither @acronym{PGP/MIME} nor @acronym{S/MIME} encrypt/signs +RFC822 headers. They only operate on the @acronym{MIME} object. Keep this +in mind before sending mail with a sensitive Subject line. + +By default, when encrypting a message, Gnus will use the +``signencrypt'' mode, which means the message is both signed and +encrypted. If you would like to disable this for a particular +message, give the @code{mml-secure-message-encrypt-*} command a prefix +argument, e.g., @kbd{C-u C-c C-m c p}. + +Actually using the security commands above is not very difficult. At +least not compared with making sure all involved programs talk with each +other properly. Thus, we now describe what external libraries or +programs are required to make things work, and some small general hints. + +@subsection Using S/MIME + +@emph{Note!} This section assume you have a basic familiarity with +modern cryptography, @acronym{S/MIME}, various PKCS standards, OpenSSL and +so on. + +The @acronym{S/MIME} support in Message (and @acronym{MML}) require +OpenSSL. OpenSSL performs the actual @acronym{S/MIME} sign/encrypt +operations. OpenSSL can be found at @uref{http://www.openssl.org/}. +OpenSSL 0.9.6 and later should work. Version 0.9.5a cannot extract mail +addresses from certificates, and it insert a spurious CR character into +@acronym{MIME} separators so you may wish to avoid it if you would like +to avoid being regarded as someone who send strange mail. (Although by +sending @acronym{S/MIME} messages you've probably already lost that +contest.) + +To be able to send encrypted mail, a personal certificate is not +required. Message (@acronym{MML}) need a certificate for the person to whom you +wish to communicate with though. You're asked for this when you type +@kbd{C-c C-m c s}. Currently there are two ways to retrieve this +certificate, from a local file or from DNS. If you chose a local +file, it need to contain a X.509 certificate in @acronym{PEM} format. +If you chose DNS, you're asked for the domain name where the +certificate is stored, the default is a good guess. To my belief, +Message (@acronym{MML}) is the first mail agent in the world to support +retrieving @acronym{S/MIME} certificates from DNS, so you're not +likely to find very many certificates out there. At least there +should be one, stored at the domain @code{simon.josefsson.org}. LDAP +is a more popular method of distributing certificates, support for it +is planned. (Meanwhile, you can use @code{ldapsearch} from the +command line to retrieve a certificate into a file and use it.) + +As for signing messages, OpenSSL can't perform signing operations +without some kind of configuration. Especially, you need to tell it +where your private key and your certificate is stored. @acronym{MML} +uses an Emacs interface to OpenSSL, aptly named @code{smime.el}, and it +contain a @code{custom} group used for this configuration. So, try +@kbd{M-x customize-group RET smime RET} and look around. + +Currently there is no support for talking to a CA (or RA) to create +your own certificate. None is planned either. You need to do this +manually with OpenSSL or using some other program. I used Netscape +and got a free @acronym{S/MIME} certificate from one of the big CA's on the +net. Netscape is able to export your private key and certificate in +PKCS #12 format. Use OpenSSL to convert this into a plain X.509 +certificate in PEM format as follows. -Also note that no signature should be more than four lines long. -Including ASCII graphics is an efficient way to get everybody to believe -that you are silly and have nothing important to say. +@example +$ openssl pkcs12 -in ns.p12 -clcerts -nodes > key+cert.pem +@end example + +The @file{key+cert.pem} file should be pointed to from the +@code{smime-keys} variable. You should now be able to send signed mail. + +@emph{Note!} Your private key is now stored unencrypted in the file, +so take care in handling it. Storing encrypted keys on the disk are +supported, and Gnus will ask you for a passphrase before invoking +OpenSSL. Read the OpenSSL documentation for how to achieve this. If +you use unencrypted keys (e.g., if they are on a secure storage, or if +you are on a secure single user machine) simply press @code{RET} at +the passphrase prompt. + +@subsection Using PGP/MIME + +@acronym{PGP/MIME} requires an external OpenPGP implementation, such +as @uref{http://www.gnupg.org/, GNU Privacy Guard}. Pre-OpenPGP +implementations such as PGP 2.x and PGP 5.x are also supported. One +Emacs interface to the PGP implementations, PGG (@pxref{Top, ,PGG, +pgg, PGG Manual}), is included, but Mailcrypt and Florian Weimer's +@code{gpg.el} are also supported. + +@vindex gpg-temp-directory +Note, if you are using the @code{gpg.el} you must make sure that the +directory specified by @code{gpg-temp-directory} have permissions +0700. + +Creating your own key is described in detail in the documentation of +your PGP implementation, so we refer to it. + +If you have imported your old PGP 2.x key into GnuPG, and want to send +signed and encrypted messages to your fellow PGP 2.x users, you'll +discover that the receiver cannot understand what you send. One +solution is to use PGP 2.x instead (i.e., if you use @code{pgg}, set +@code{pgg-default-scheme} to @code{pgp}). If you do want to use +GnuPG, you can use a compatibility script called @code{gpg-2comp} +available from +@uref{http://muppet.faveve.uni-stuttgart.de/~gero/gpg-2comp/}. You +could also convince your fellow PGP 2.x users to convert to GnuPG. +@vindex mml-signencrypt-style-alist +As a final workaround, you can make the sign and encryption work in +two steps; separately sign, then encrypt a message. If you would like +to change this behavior you can customize the +@code{mml-signencrypt-style-alist} variable.
